What is Clearlogx? The Clearlogx Process is a patented technology that precisely and continuously controls the feed of specialty chemicals used in water treatment, in order to maintain optimized chemical performance while simultaneously improving overall treatment process efficiency.

Observations Of Chemical Control and Related Filter Enhancement Lead to Clearlogx Devlopment

While monitoring a low pressure membrane trial that was experiencing rapid fouling due to a highly contaminated water source, the inventor noticed intermittent periods of significant fouling reduction. It became apparent that membrane fouling was directly related to the accumulation of particles on the membrane elements. Higher coagulant dose results in a higher cationic particle charge coming into contact with a membrane element possessing an anionic charge. As opposite charges attract, particulate accumulation is the result. Maintaining pH, particle charge and temperature could cease this accumulation and a significant reduction in fouling can be maintained.

Existing chemical control technologies such as streaming current and zeta potential are limited to controlling the coagulant dose alone. These analyzers measure incoming turbidity (anions) and offset with an equal charge value of coagulant (cations). During periods of low turbidity and higher organic loading, this system of chemical feed will not allow the required higher dose.

Clearlogx provides for coagulant feed based on the amount required to mitigate turbidity as well as soluble organic removal (enhanced coagulation) for TOC and DBP compliance. Variables such as flow, organic load, temperature and detention time calculate proper coagulant dose. Particle charge and pH are controlled by dosing acid or base via a streaming current or zeta potential signal.
